摘　　要：为了研究土-结构相互作用对东深工程中三种不同类型渡槽结构地震响应的影响,针对工程场址土层的特点, 文中对采用有限单元法进行土层动力分析时选取土层有限范围的问题进行了讨论。All of three types of aqueduct structures in Dongshen Engineering are built on soil-site. The effects ot dynamic soil-structure interaction must be considered in the seismic analysis of the structures. Therefore, the problem of reasonable range cut from the semi-infinite soil-site must be met and required to determined, when the finite element method is applied to analyze the dynamic response of the soil-site under the seismic excitation. This problem is discussed in this paper by numerical analysis according to the characteristics of the soil-site.
